By material (resin particle) from hopper 56, introduce cylinder body 22.When screw rod 24 rotates in the cylinder body 22 by heater 23 heating, when transmitting material, rub this material.Therefore, material melts and collects at the far-end of cylinder body 22.
If the material that collects scheduled volume at the far-end of cylinder body 22 is with for injection, actuating screw advances-motor 72 of retraction mechanism 28.Then, by transport tape 74, make pulley 76 rotations, make by this threaded portion 80 rotations.Thus, make to travel forward with the nut portion 82 of threaded portion 80 screw-threaded engagement.The main part 60 of rotary screw 26 is bearing on the second track 58 slidably by stay 68.Therefore, if nut portion 82 travels forward, pulley 66 travels forward along the second track 58 by force cell 70.When screw rod 24 advances in this way, make the material in cylinder body 22 inject set of molds by nozzle segment 54, this set of molds is clamped by device for clamping mould 14.
In the present embodiment, the plane Y(Fig. 3 that comprises the corresponding slidingsurface of left the second track and right the second track 58) be positioned between the rotating shaft 67 of screw rod 24 and motor 62.Specifically, the level error between the slidingsurface of the gravity position of rotary screw 26 and the second track 58 is less.Therefore, when rotary screw 26 travelled forward along the second track 58, it can slide smoothly along the second track 58, and without vertically deflection.Therefore, being connected in the screw rod 24 of rotary screw 26 can be in cylinder body 22, along axis X 1, move smoothly.
If the material in cylinder body 22 injects set of molds by nozzle segment 54, its reaction force acts on along the axis X 1 of screw rod 24.This reaction force is passed to pulley 66 from the rear end of screw rod 24, and by bearing 61, further is passed to the main part 60 of rotary screw 26.Thus, extruding force cell 70.Nut portion 82 is positioned on the apparent surface of force cell 70 with respect to screw rod 24.This nut portion 82 and threaded portion 80 screw-threaded engagement.
Therefore, when from two axial side extruding force cells 70, measure the pressure that puts on screw rod 24.To be delivered to controller from the output signal of measuring transducer 70, determine by this whether set of molds is filled with resin of scheduled volume and so on.
If complete pressurization after under predetermined pressure, resin being poured to set of molds, injecting unit 12 is carried out mold cycle subsequently constantly, therefore remains nozzle touching state.In this state, rotary screw 26 makes screw rod 24 rotation, meanwhile screw rod advance-retraction mechanism 28 retracts screw rod 24, thus, again material injected to the far-end of cylinder body 22.If deviate from product after set of molds is opened by device for clamping mould 14, again make the set of molds closure, to carry out next mold cycle.
In mold cycle, rotary screw 26 moves along the second track 58, and this second track 58 is parallel to tie-rod 37 and arranges.Therefore, rotary screw 26 can move smoothly, thereby screw rod 24 can move smoothly repeatedly along axis X 1.
In the present embodiment, comprise that the sliding part 69 on the respective end 59B of supporting member 59 of the second track 58 can be with respect to tie-rod 37 axially-movables.Therefore, even if following distortion occurs: tie-rod 37 is elongated by the reaction force that produces when by nozzle segment 54 injection material, because sliding part 69 moves along the axis X 2 of its corresponding tie-rod 37, thereby can absorb this distortion.In addition, if tie-rod 37 bendings, anti-distortion here is passed to supporting member 59, thereby supporting member can be remained linearity.Therefore, the distortion of tie-rod 37 is not passed to the second track 58.Therefore, can accurately remain the linearity of the second track 58 and the depth of parallelism between track 58, thereby in injection process, screw rod 24 is moved back and forth smoothly.
It is hereinafter the description of how to rotate for injecting unit 12.
By activating pushing mechanism 30, so that threaded portion 49 moves along second direction, and injecting unit 12 is moved backward.Carry out this kind motion, between the injecting unit 12 that prevents device for clamping mould 14 and be rotated, to interfere.Then, by unclamping screw 48, base portion 32 and framework 34 are broken away from each other.Because framework 34 is arranged on base portion 32, if therefore framework 34 breaks away from from base portion 32, it can rotate around fulcrum post 46.
Fig. 4 is illustrated in the framework 34 of injecting unit 12 with respect to the state after base portion 32 rotations of mainframe 20.The injecting unit 12 of the present embodiment can be along horizontal plane P(Fig. 1) around fulcrum post 46, rotate, this horizontal plane is between base portion 32 and framework 34.For example, in clean or replacement cylinder body 22 and/or screw rod 24, carry out this kind rotating operation.When injecting unit 12 rotated, back leg 43 can slide along the horizontal plane P of base portion 32 tops.Therefore, injecting unit 12 can easily and safely rotate.
As mentioned above, according to the injection (mo(u)lding) machine of the present embodiment, comprise the antetheca 35 of framework 34, rear wall 33 and the tie-rod 37(side member of framework 34), cylinder body 22 is arranged on antetheca 35, and screw rod advances-and retraction mechanism 28 is arranged on rear wall 33, and tie-rod connects antetheca 35 and rear wall 33.This injection (mo(u)lding) machine also comprises supporting member 59 and rotary screw 26, and this supporting member 59 comprises the second track (guide) 58 that arranges along tie-rod 37, and rotary screw 26 can move along the second track 58.An end 59a of each supporting member 59 is fixed in framework 34 by standing part, and this standing part comprises fixture 63 or bolt.Another end 59b of each supporting member 59 is bearing on its corresponding tie-rod 37, for the sliding part 69 by as movable part, is parallel to screw rod 24 motions.
Therefore, even if tie-rod 37, because the reaction force that produces in injection process is out of shape, can be remained the linearity of the second track (guide) 58.Therefore, rotary screw 26 can firmly move along the second track 58, thereby screw rod 24 can firmly move along the second track 58.Can standing part be fixed in to framework 34 by some other fixtures except bolt.In addition, each sliding part 69 can be arranged on an end 59a of its corresponding supporting member 59, and another end 59b is fixed in rear wall 33 by fixture.In addition, guide and supporting member can form as one.
